Circuit Specialists (US) used to sell something similar to the link
below for $29.00. Works pretty well, a 6"X6" board etches in about 5
minutes with fresh etchant. Basically a hands free operation and with
the right etchant you see the progress on both sides of the board.
Unfortunately, now, for that price there's no included heater. The
aquarium pump and heater can be had at a pet store for those
undertaking a similar but cheaper route.
